METHOD FOR CONTINUOUS STEEL CASTING

A method for continuous steel casting is provided which can reduce the center segregation that occurs in slabs. In this method for continuous steel casting, defining a first interval within an interval in the slab drawing direction inside a continuous caster as the interval from a starting point where the average value of the solid phase rate along the thickness direction in the width center of the slab 18 is between 0.4-0.8, to an ending point where the aforementioned average value of the solid phase rate along the thickness direction in the width center of the slab is greater than the average value of the solid phase rate at the starting point and less than or equal to 1.0, the water density per surface area of the slab is set in the first interval between 50 L/m2xmin and 2000 L/m2xmin) and the slab is cooled by water. 本发明提供一种可减少在铸片内产生的中心偏析的钢的连续铸造方法。本发明所涉及的钢的连续铸造方法是，在连续铸造机内的沿着铸片拉制方向的区间，将从铸片(18)的宽度中央的沿着厚度方向的固相率的平均值在0.4～0.8的范围内的起点、到在上述铸片宽度中央的沿着厚度方向的固相率的平均值比在上述起点的固相率的平均值大且为1.0以下的范围内的终点设为第一区间，在上述第一区间内，将铸片单位表面积的
